Server setup

<disableac></disableac>

Comma separated list of disabled anti-cheats. This setting disables specific AC codes. If a detection is triggered and it's not disabled by the server, a player will get kicked and be shown the AC code corresponding to that detection.

Please note that this will only void the AC # kick for using GTA singleplayer cheats and some very basic, outdated and patched MP cheats (such as s0beit). Hacks & cheats designed for MTA may trigger a Global ban.
If you try to use a typical MTA cheat under the belief using disableAC will save your day, and get banned for a while, it's your own fault, regardless of this setting being used to disable any of the AC classifications that it may fall under.

Available codes are:

Code for <disableac>

Displayed on detect

Required server version

Detects presence of trainer. Capital letters in the message are for tagging particular trainers

<enablesd></enablesd>

Comma separated list of enabled special detections. A special detection is a type of anti-cheat for (usually) harmless game modifications. Competitive servers or servers dealing with a certain problem structurally may wish to enable special detections, but most servers should leave this setting blank. Available codes are:

Disallow disabled anti-cheat components. This is triggered when an anti-cheat component can not start. It is usually due to some problem with the PC and might be fixed by a reboot. Can also be triggered by a virus.

Disallow non-standard gta3.img or gta_int.img (For servers not using onPlayerModInfo)

We are constantly working on keeping the definitions for above SD (special detections) up-to-date, so as to ensure all violating software or circumstances that you opt-in to disable gets detected once used. While we are pro-actively checking if new or unknown software/tools are still being detected under the same signature, it's possible that something slips through the cracks. Therefore, you can help us if you come across anything that should be detectable using SD # but is not currently; send a forum PM to Dutchman101 or ccw with your report.

<client_file name="data/carmods.dat" verify="0"/>

By default, clients may not join a server if they have customized GTA:SA data files. Adding one or more of the above lines excludes files from validation. The file names that can be used are:

"data/carmods.dat"

"data/animgrp.dat"

"data/ar_stats.dat"

"data/melee.dat"

"data/clothes.dat"

"data/object.dat"

"data/default.dat"

"data/surface.dat"

"data/default.ide"

"data/gta.dat"

"data/surfinfo.dat"

"data/peds.ide"

"data/vehicles.ide"

"data/pedstats.dat"

"data/water.dat"

"data/txdcut.ide"

"data/water1.dat"

"models/coll/weapons.col"

"data/weapon.dat"

"data/plants.dat"

"anim/ped.ifp"

"data/furnitur.dat"

"data/procobj.dat"

"data/maps"

Note 1:"data/maps" represents all the files and directories within "data/maps"

Client

Disabled AC contains the contents of the server setting from <disableac></disableac>
Enabled SD contains the contents of the server setting from <enablesd></enablesd>
Allowed client files contains numbers to indicate which client files the server allows to be modified. The numbers represent these files:

1 - "data/carmods.dat"

2 - "data/animgrp.dat"

4 - "data/ar_stats.dat"

5 - "data/melee.dat"

6 - "data/clothes.dat"

7 - "data/object.dat"

8 - "data/default.dat"

9 - "data/surface.dat"

10 - "data/default.ide"

12 - "data/gta.dat"

13 - "data/surfinfo.dat"

14 - "data/peds.ide"

15 - "data/vehicles.ide"

16 - "data/pedstats.dat"

17 - "data/water.dat"

18 - "data/txdcut.ide"

19 - "data/water1.dat"

20 - "models/coll/weapons.col"

21 - "data/weapon.dat"

22 - "data/plants.dat"

23 - "anim/ped.ifp"

24 - "data/furnitur.dat"

25 - "data/procobj.dat"

26 - "data/maps"

Note:If the info is marked "Undisclosed", it means that the server has decided not to disclose the AC info to the client.

Using modified files

If you want to use modified data files from your GTA:SA install directory, check this check box:

Settings -> Multiplayer -> Use customized GTA:SA files

(checkbox only appears if your GTA:SA data files are customized)

Note:This will restrict your access to some public servers as most do not allow customized data files.

AC Panel resource

An anti-cheat helper resource called acpanel is included with the default resources.

It shows the current anti-cheat status of your server, along with an option to keep your clients up to date and a basic implementation of onPlayerModInfo to block modified img files.

AC Guide purpose

The toolset available to server owners, as described in the AC guide, is intended to provide methods to reduce several types of unfair advantage that a player may get over others.
It is not related to core MTA anti-cheat (the way we continuously fend off hackers using cheats designed for MTA), which you cannot exercise any control over (more on that is listed in the <disableac> header at the beginning of this page).

The definition of 'preventing unfair advantage' truly depends on the type of server (gamemode) and competitiveness. You always got to think out a custom approach depending on your server's needs.
Good examples of what is possible for you to achieve and to what sort of gamemode they belong;

- Disabling client GTA mods (custom gta3.img) to prevent any sort of "small skin" abuse (a form where the player's skin has a small hitbox, while the attacker's screen shows it as if bullets collided anywhere).
Removed world objects to gain unfair advantage in maps or areas where combat takes place, in order to easily see (or shoot) through them, or vehicle mods which have been stripped of its collisions, are also combatted by these means.

- Disabling mouse and keyboard button macro's using SD #31 & 32 if you have a server revolving around melee combat (mostly for "binds" enabling easy stealthkills using macro combinations rather than natural skill).

Also, with SD #31 and #32 you can prevent mass-firing of performance-intensive serverside function calls. Without using this, and if your gamemode doesn't gave proper timer management, it is possible for malicious players to create macro binds (e.g commands bound to call serverside functions) and induce server lag by massively triggering them, for example 1000 times a second using a macro capable of doing so. This is not related to gaining unfair advantages, but your gamemode's existing code measures make or break the feasability of blocking macro key or mouse button inputs.
